WATCHMAN"S TIME-RECORDING CLOCK.

Application filed November 13, 1924. Serial No 749,682.

My invention relates to time recording clocks of the character embodiedin my copending application Serial No. 749,681, filed Nov. 13, 1924, andmore particularly, al

though not necessarily, to time recording clocks for use by watchmen.

It is a purpose of my invention to provide a time recording clockincluding a dial movable by suitable clock mechanism, and extremelysimple, inexpensive and durable means for punching the dial, such meansbeing manually operable by the watchman or operator and in such manneras to prevent the possibility of tampering with or injuring the elementscomprised in such means.

It is also a purpose of my invention to provide a clock of the abovedescribed character in which the dial, operating mechanism therefor, andthe said punching means are accessible only through the opening of adoor on the casing, and a second punching instrument operable uponopening the door whereby the record of such fact is made upon the dial.

I will describe only one form of time recording clock embodying myinvention, and will then point out the novel features thereof in claims.

In the drawings,

Figure 1 is a view showing in front elevation, with portions thereofbroken away and other portions in section, one form of time recordingclock embodying my invention;

Figure 2 is an enlarged plan view showing the mechanism for actuatingone of the punching instruments embodied in the clock shown in Figure 1;

Figures 3 and 4 are sectional views taken on the lines 3-3 and 44,respectively, of Figure 1.

Referring specifically to the drawings, in which similar referencecharacters refer to 45 similar parts in each of the views, my invention,in its present embodiment, com- ,prises a casing 15 provided with a door16 having a transparent panel 17 through which certain of the contentsof the casing 50 can be readily viewed. The casing in the presentinstance is of circular form, and

mounted axially thereof is a shaft 18 to which is fixed a dial 19adapted to be continuously rotated in a clockwise direction by means ofsuitable clock mechanism. As this clock mechanism is conventional, ithas not been shown. The dial 19 is provided with radial graduations,certain of which are numbered to designate the twenty-four hours of aday, while the intervening graduations designate fractions of the hours.The dial 19 is preferably formed of paper or other material. which iscapable of being readily perforated.

As illustrated to advantage in Figures 2 and 3, a U-s'haped frame 20 issecured at its ends in horizontal position within the cas ing 15, and tothe intermediate portion of this frame is secured a metallic body 21 bymeans of screws 22. One of the screws extends through the frame and bodyand also through an L-shaped yoke 23, the vertical portion of whichprovides a limiting or keeper arm 24 provided with openings 25 and 26.The arm 24: is disposed in spaced parallel relation to the lower side ofthe body 21 so as to accommodate and permit unrestricted movement of thedial 19 therethrough.

A punching instrument 27 is mounted for sliding movement within frame 20and the body 21, and this instrument is provided with a recessed end toform divergent blades 27 which, on the movement of the instrumentthrough the dial, forms a clean per foration in the dial. The inner endof the instrument 27 is formed with an up-turned hook 28 engaged by acrank 29 secured to a shaft 30 journaled in the parallel portions of theframe 20 and provided at one end with an angular extension 31 which isconnected to a spring 32 for normally urging the shaft to a position inwhich the instrument 27 occupies an inactive or non-punching position,as illustrated in Figure 3. The opposite end of the shaft 30 is bent toprovide an angularly disposed arm 33 provided with a flattened end 31disposed in partly spanning relation to the inner end of a sleeve 35fixed to and extending through the periphery of the casing 15.

A key 36 is adapted to be inserted into locking spindle at.

the sleeve 35, and when forced inwardly engages the flattened end tomove the arm 83, and consequently the shaft 30, to actuate the crank 29in moving the instrument 2? forwardly to active position in which thebladed end 2'? pierces the dial 19 and reposes within the opening 26 ofthe arm 2%. It is to be noted that the position of the flattened end 3%with respect to the sleeve is such that when forcing the key inwardly itwill ride offof the fatten d end. owing to the turning movement of thearm 33 so that the possibility of bending, distorting or in any wayinjuring the key, arm or the mechanism operated by the arm is prevented.The key 36 is constructed to "provide a shoulder 37 which is adapted toengage the outer end of the sleeve 35 so as to limit the inward movementof the key.

Fort-he purpose of recording the surreptitious opening of the doorshould anyone attempt to alter the true record made on the dial by thepunching instrument 27, I have provided a second punching instrument 3S,whichis mounted for sliding movement in the frame 20 and the body 21above the punching instrument 2?. and in such manner as to pierce thedial 1!) when moved forwardly from the position shown in Figure Thisinstrument is provided with cutting end identical to the end 27 of theinstrument 2?, and its inner end is provided with a downwardly turnedhook 39 engaged by a crank tOfixedto a shaft s1, journaled in the frame20 andbent at one end to provide an angularly disoosed arm 4-2, which atall'times engages an arm d3 fixed to a spring 45 normally urges theshaft to a position in which the punching instrument 38 occupies theinactive position shown 'in Figure 3, and the arm i2 into engagementwith the arm 43.

The locking spindle it is rotatably mounted in a sleeve io' extendingthrough the pe riphery of the casing 15. The locking spindle stiaisflattened adjacent one end to provide a rotatable locking bolt i? whichis adapted to be engaged by a keeper fixed to the door 16. The slee' 'e-it3 is slotted at two points as indicated at at to receive the keeper-18 and to permit the lock bolt e)? to engage the keeper and thus securethe door in closed position. The angular end -19 of the spindle i lprovides means by which key 50 can rotate tne spindle to move the lockbolt -17 to locking or releasing po sition with respect to the keeperL8. Through the medium of the arms 42 and 13, the spring functions tonormally urge the spindle l t to a position in which the lock bolt 4.?engages the keeper to prevent the opening of the door. However when thespindle is rotated through the medium of the key 50 to move the bolt l?to releasing position with respect to keeper, the arm is moved toactuate the arm -12 and thus r0- tate the shaft against the tension ofthe spring iii to shift the punching instrument 38 from active toinactive position, thereby eiiccting a perforation of the dial 19 andthus recording the fact that the lock has been actuated and the dooropened.

In practice, the dial 15) is adapted to be punched at prearrangedintervals by the watclnnan through the use of the key 36 to operate thepunching instrument 27 in the manner previously described whereby theperforation formed in the dial as the result of this operation makes apermanent record on the dial. Should the *atchman attempt to tamper withany of the mechanism for actuating the dial or thepunching instrument,it will be manifest from the preceding description that upon opening ofthe door 16 the dial will be perforated by the punching instrument 38 torecord the fact.

Although I have herein shown and described only one form of timerecording clock embodying my invention, it is to be noted that variouschanges and modifications may be made without departing from the spiritof my invention and the spirit and scope of the appended claims.

I claim as my invention:

1. A time recording clock comprising a casing, a dial movable in thecasing, a perforating instr ment movable in the casing to perforate thedial, a shaft operatively connected to the instrument and movable toactuate the latter, means for yieldably urging the shaft toa position'inwhich the instrin'nent occupies non perforating position an angularlydisposed arm on the shaft, and a sleeve extending through the casingtopermit the insertion of a key into the casing and into engagementwithsaid arm in a manner to actuate the shaft for operating the instrumentand perforating the dial.

2. A. time recording clock comprising a casing, a dial movable in thecasing, a perforating instrument in the casing for perforating the'dial,a shaft operatively c0nnected to the instrument, means for yieldably uring the shaft to a position in which the instrument occupies anon-perforating position with respect to the dial, said casing beingformed with an opening, and an angular extension on the shaft'disposedadjacent said opening whereby a key inserted in the opening will engagethe extension and turn the shaft to move theinstrument to perforatingposition against the action of said urging means.

A time recording clock comprising a casing, a dial movable in thecasing, a perforating instrument in the casing for perforating the dial,a shaft operatively connected to the instrument. means for yieldurgingthe shaft to a position in which LLL/LY the instrument occupies anon-perforating position with respect to the dial, a sleeve extendingthrough and fixed in the casing, an extension on the shaft having itsfree end in spanning relation to the inner end of the sleeve so thatwhen a key is inserted into the sleeve the extension will be engaged toactuate the shaftand move the instrument to perforating position, andunder movement of the shaft the extension will be 10 moved out of thepath of movement of the key for the purpose described.
